Data which includes observations and other metrics are uploaded to a national server which is then compiled into the National Digital Forecast Database. Weather stations as well as the public can download this information from the database.
The nationwide network of radio stations broadcasting continuous weather information from the National Weather Service is called NOAA Weather Radio. It provides real-time weather alerts, forecasts, and other emergency information to the public 24 hours a day.
Surface temperature information comes from a network of primarily automated weather stations. Upper air data come from 12-hourly weather balloons (radiosondes) and numerous remote sensing inputs.
The National Weather Service has offices around the country mostly at airports that gather information such as temperature, humidity etc all funded through your tax dollars. Radar and satellite are also provided by the NWS. Weather information is gathered by the NWS and made public.

The NWS also collaborates with other meteorological organizations and agencies to enhance the quality and coverage of its weather information.
Satellites. 2nd answer: There is a network of weather reporting stations in the US - many of them at airports - who report temperature, visibility, dew point, wind strength and direction, barometer readings, and so forth to the National Weather Service. Using this information, along with satellite photos and RADAR readings, they draw up and analyze weather maps.
The National Weather Service makes weather maps with special lines. Isotherm is a line that connects points of equal temperature. Isobar is a line that is drawn to connect equal atmosphere pressure.
The National Weather Service tracks the weather and the reporters get the weather from them for local areas. You can see weather reports from the National Weather Service on line and can get weather for any spot in the world.
